matter.
A tentative conclusion may be inferred that the airborne contamination hazard is relatively less serious than
previously, believed.

:
Instrumentation on the YAG-40 was on the whole
successful although only partial results were obtainable on
5 out of the 19 air samplers, while 3 out of 5 were {noper~
ative on the YAG~39.
All the samples taken have been returned
to USNRDL for evaluation.

Air Monitor:
A prototype of a semi-portable air monitoring unit
designed for future shipboard and/or land use were evaluated.
Time intensity records of airborne beta contamination were
taken.
Present instrument gives adequate warning against
airborne hazards in external fields up to 1 r/nr.
can be given within a minute of arrival of hazard.
This warning
Instrument
appears useful also to forewarn ships, land stations, etc., of
possible background level buildup.
Personnel Protection Studies and Radiological Safety
During the YAG recovery operations, the greatest
dose rate observed was eboard the YAG-4+0 and wes estimated to
be 10 r/hr at H+30.
The USS MOLALA (ATF 106) personnel in-
volved with the recovery of the YAG-4+0 received an average
dose of 200 mr.
During the decontamination operations the total dosage
